Augrented Insights Report for 501 Dean Street

501 Dean Street is a four-story, eight-unit Old Law Tenement building located in Prospect Heights, Brooklyn, and owned by 501 Dean St LLC. The building has experienced significant maintenance issues in 2025, with multiple complaints regarding heat and hot water problems affecting the entire building between April and May 2025, resulting in violations. There were also several unresolved electrical and plumbing issues reported in May 2025, including problems with outlets, an electric/gas range, and a bathtub/shower.

The building has active violations related to failure to file annual boiler inspections from 2018-2024 and an illegal conversion case involving unauthorized duplexing of an apartment that remains under active status with a $6,250 penalty. The property has documented pest and maintenance challenges, particularly in apartment 3L, which has multiple open violations including rodent infestations (both mice and roaches), defective light fixtures, and issues with safety devices such as smoke and carbon monoxide detectors. While the building filed annual bedbug reports from 2020-2024 showing no infested units, there have been persistent rodent concerns, with multiple inspections revealing rat activity between 2017 and 2021.

Several maintenance requests from 2025, including for heat, hot water, and various appliances, have been closed due to inability to gain access for inspection. The building's infrastructure concerns are further underscored by multiple Department of Buildings violations for failure to file external low-pressure inspections from 2018-2024, though some infrastructure-related violations from 2022-2023 have been resolved, such as repairs to broken wood subflooring and window issues in apartment 3L. (Note: This summary provides a comprehensive overview of the building's documented issues while adhering to legal compliance requirements.)
